plane, the coordinate transformation relation between the ground coordinate system and the camera image coordinate system is deduced in detail, and the conversion relationship between the camera image coordinate system and the computer pixel coordinate system is analyzed. and the similarities and differences between the coordinate transformation and the camera calibration; Finally, a moving object tracking method based on image processing is proposed

Here we can get the user's login name and the thread ID value. Then with Binlog, we can trace the operation time of each operation statement, operator, etc. Implement audits.

Absrtact: For the increasingly rampant denial of service (DoS) attacks on the Internet, this paper analyzes the performance defects of the traditional random data packet tagging algorithm, proposes a new return tracking algorithm based on hash message authentication code, and hppm that the algorithm improves the efficiency and accuracy of the return tracking
The camera tracking feature of Unity 2D game development TutorialIn the previous chapter, we created a simple 2D game. The sprite in this game has 3 states: idle, left, and right. This looks really cool! But the only 3 states limit the ability of the genie and the imaginary space of the game logic. It seems necessary to let the Elves have more state, and this is the main content of this chapter to explain.Camera T

For a set of sampled data, the histogram method usually divides the value of the data into several equal intervals, the data is divided into several groups according to the interval, the ratio of the number of each set of data to General staff is the probability of each unit; The kernel density estimation method is similar to the Histogram method, but it has a

I,OracleTracking FileThere are three types of Oracle tracking files:
One is the background alarm log file, which recordsDatabaseActivities of background processes during startup, shutdown, and running, such as creating tablespaces, creating rollback segments, some alter commands, log switching, and error messages. When the database fails, you should first check the file, but the information in the file is not necessarily related to any error status.

Block chage tracking is a new feature of Oracle10g. The block change tracking process records the changes in data blocks since the last 0-level backup and records the information in the tracking file. RMAN uses this file to determine the changed data to be backed up in the Incremental backup. This greatly improves the backup performance and speed. RMAN can no lon

DDoS attack tracking
Distributed denial of service (DDoS) attacks are a serious threat on the internet. However, the memory-free functionality of the Internet routing mechanism makes it difficult to trace the source of these attacks. Therefore, there is no effective way to deal with this problem so far.
The common way to trace DDoS attacks is IP tracing, which is designed to identify the real IP address that generates the attacking packet host. Typica
